FCC NOTICE: The equipment described in this manual generates, uses, and may emit radio
frequency energy. The equipment has been type tested and found to comply with the limits for
a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are designed
to provide reasonable protection against such radio frequency interference when operated in
a commercial environment. Operation of this equipment in a residential area may cause
interference, in which case the user at his own expense may be required to take measures to

Chapter 1
System Overview
DECsystem 5500 systems house all components in a BA430 enclosure. This
enclosure is a free-standing pedestal that houses the following:
• Card cage
• System controls
• Central processing unit (CPU) module set
• Memory modules
• Communications controller modules
• Tape drive controller module
• Console module
• RF-series or RZ-series Integrated Storage Elements, or both
• TK70 tape drive or TLZ04 tape drive
• Power supply
• Fans
Up to four storage devices in the following combinations can be mounted
inside the BA430 enclosure:
• Four RF-series or RZ-series Integrated Storage Elements (ISEs), or a
combination of both
• One tape device, the TK70 or TLZ04 tape drive, and up to three RF-
series or RZ-series ISEs, or a combination of both
This chapter describes the system components and their functions.
Chapters 2 and 3 describe how to use the system and options.
System Overview 1–1

1.1 Front View and Physical Description
The front of the system has a divided door that restricts access to the system
controls. Figure 1–1 shows the system with the front door closed.
Figure 1–1: DECsystem 5500 System
MLO-004032
A three-position rotary lock allows you to lock both the upper and lower
doors, or to lock just the lower door. Opening the upper door allows you to
access the controls for the storage devices and the System Control Panel
(SCP). Opening the entire door allows you to access all system controls and
cable connections.
Figure 1–2 shows the three key positions and the controls accessible in each
position.

Opening and Closing the Divided Door
The divided door allows you to access the mass storage devices and system
control panel (SCP), while restricting access to the power switch and the
console module. Open and close the door as follows:
1. Insert the key in the lock on the front door. Turn the key to the top
position (Figure 1–3) to open just the upper portion of the door, or to
the bottom position (Figure 1–4) to open the entire door.
With the key in the bottom position, the upper and lower doors will
open together.
2. Swing the door open.
3. To close the door, simply reverse the procedure. When pushing the
doors closed, push gently at the top right of the upper door and the
bottom right of the lower door.

1.1.1 The BA430 Enclosure
Opening the front door enables you to access the components housed in the
BA430 enclosure. Figure 1–5 shows a typical configuration.
The BA430 enclosure can contain the following:
• Mass storage —
• TK70 or TLZ04 tape drive and up to three RF-series or RZ-series
ISEs, or a combination of both
• No tape drive and up to four RF-series or RZ-series ISEs, or a
combination of both
All DECsystem 5500 systems contain the following:
• System Control Panel (SCP)
• Card cage containing modules — CPU, memory, communications
controllers, mass storage controllers
• CPU cover panel
• Power supply
• Fans

1.1.1.1 Mass Storage Shelf
The mass storage shelf extends across the top of the enclosure. The shelf
contains a system control panel (SCP), tape device, and up to three RF-
series or RZ-series ISEs (tapeless systems can have up to four ISEs). Each
ISE has its own panel with controls and indicators. Instructions for using
mass storage devices are in Chapter 3. The SCP is to the right of the
storage devices. Figure 1–6 shows the mass storage shelf.
NOTE: RZ-series hard disk drives do not have controls or indicators on
their front panel.

DC OK Indicator
Over Temperature
Warning Indicator

Restart Button
The SCP has two indicators: the DC OK indicator and the Over
Temperature Warning indicator. The green DC OK light indicates that the
power supply voltages are within the correct operating range. If the DC OK
indicator is not lit when the system power is on, refer to the DECsystem
5500 Troubleshooting and Diagnostics manual included in the Customer
Hardware Information Kit.
The red Over Temperature Warning indicator flashes to indicate that the
system’s internal temperature is approaching a level that may cause system
components to overheat. In addition to the flashing Over Temperature
Warning light, an audible alarm also provides warning of a possible over
temperature condition. If the components continue to heat, the system
will automatically shut down to prevent components from being damaged.
Chapter 2 provides instruction for turning on the system after a preventive
shutdown due to overheat conditions.
1–8 DECsystem 5500 Operation

Below the indicators are the Halt and Restart buttons. The Halt button
is a two-position button. When you press the button, the system halts.
A red indicator on the Halt button lights when the button is set to the
in position. Before you can enter console commands, you must press the
Halt button again to return it to the out position. When the Halt button
is returned to the out position, the console mode prompt (>>) is displayed
on the console terminal screen. Now you can enter console commands. If
you inadvertently press the Halt button, enter continue Return to continue.
Chapter 2 describes halting the system in more detail.
CAUTION: Pressing the Halt button halts the system regardless of the
setting of the Function switch on the console module.
Below the Halt button is the Restart button. The Restart button has a
green indicator. When you press the Restart button, the system returns to
a power-up condition and self-tests are run. If the bootmode variable is set
to aand you have assigned a value to the bootpath environment variable,
the system will reboot system software. Chapter 2 contains additional
instructions on restarting your system.
NOTE: The Halt and Restart buttons can be disabled to prevent accidental
activation. Contact your Digital service representative if you want to disable
the controls on the SCP.
1.1.1.2 Card Cage
The modules in your system are mounted in a 12-slot card cage under the
mass storage shelf, as shown in Figure 1–7.
System Overview 1–9

Figure 1–7: Card Cage
MLO-005182
Slots 12 - 1
The central processing unit (CPU) module set is installed in slots 1 and 2
with its associated memory module in slot 3. Additional memory modules
may be installed in slots 4 through 6. Remaining slots are available for
Q-bus option modules.
The number and type of modules installed in your system depend on your
configuration. Each Q-bus slot, even an empty one, is protected by a module
cover. Together the covers form a shield. The purpose of the shield is as
follows:
• To protect external devices from electrical interference generated by the
system
• To protect the system from electrical interference generated by external
devices
• To maintain air flow integrity
CAUTION: Do not operate the system without Digital-supplied module
covers. The covers are required to protect the equipment and to meet
1–10 DECsystem 5500 Operation

international regulatory standards. Do not substitute other module covers
as they may not meet the required specifications.
Operating the system without the module covers has the following
consequences:
• The system may overheat due to improper air circulation.
• The system will not comply with FCC and VDE requirements for
electrostatic shielding and may produce electrical interference that
affects other equipment.
• The system is susceptible to electrical interference or damage from
external sources.
The design of the module covers varies, depending on the type of module
installed in the slot. Modules requiring external cable connections, such as
communications controllers, have recessed covers that are riveted directly
to the module. The recessed module covers allow space for connecting
cables. Modules requiring no external cable connections, such as mass
storage controllers, are covered by flush covers. Empty slots are also
covered by flush covers which may be single or double width. All covers,
except those covering empty slots, have a label identifying the module
installed in the slot.
Cables connecting your system to peripheral devices (such as terminals,
modems, and printers) are attached to communications controllers. Each
cable can contain multiple lines. The cables run under the BA430 enclosure
and out the back or side of the enclosure, where the cables are split into
individual lines. Chapter 3 describes these connections in more detail.
